Keep Your AI Grounded in Reality

Grounded Docs MCP Server eliminates AI hallucinations by providing always-current, version-specific documentation to your AI coding assistant.

​
Why Grounded Docs?

The open-source alternative to Context7, Nia, and Ref.Tools.

Up-to-Date Context

Fetches documentation directly from official sources on demand, ensuring your AI always has current information.

Version-Specific

Queries target the exact library versions in your project, eliminating version mismatch issues.

Reduces Hallucinations

Grounds LLMs in real documentation from official sources, dramatically reducing false information.

Private & Local

Runs entirely on your machine. Your code never leaves your network.

​
